The reporter learned from the China National Space Administration that at 19:52 on February 10th, Beijing time, the Tianwen-1 probe implemented the near fire capture brake, and the 3000N orbital control engine of the orbiter ignited for about 15 minutes, and the probe entered the near fire smoothly. The point height is about 400 kilometers, the period is about 10 Earth days, and the large elliptical orbit of fire with an inclination of about 10°. It has become China's first artificial Mars satellite, achieving the goal of "orbiting, landing, and patrolling." , Orbiting Mars successfully.
After China’s first Mars exploration mission entered the Mars capture phase from the ground fire transfer phase, the medium-resolution cameras, high-resolution cameras, magnetometers, mineral spectrometers, ion and neutral particle detection and detection carried by the Tianwen-1 orbiter Loads such as energy particle detectors will begin to work one after another to conduct multi-dimensional exploration of Mars.
Since its successful launch on July 23, 2020, the Tianwen-1 probe has flown for 202 days, completing one deep-space maneuver and four midway corrections.
When it arrived on Mars, the Tianwen-1 probe had a flight distance of about 475 million kilometers and a distance of about 192 million kilometers from the earth. The one-way delay of the communication between the device and the ground was about 10.7 minutes, and the systems were in good condition.
The follow-up Tianwen-1 probe will also undergo several orbital adjustments, enter the Mars moored orbit, and carry out pre-selected landing zone exploration. It is planned to choose an opportunity to land on Mars from May to June 2021 and carry out inspections.
